Arduino Weather Station || DHT 11

I build a Arduino Weather Station. It uses a DHT 11 ( it will also work with DHT21 DHT22)

Step 1: Video

I also explain everything in this video. So it might be easier for you if you watch it!

Step 2: First Sketch

The first sketch displays the sensor values to the Serial Monitor

• Sensor:

pin 1 - 5

pin2 - 5v

pin3 - GND

Step 3: Second Sketch

In this sketch we are going to display the values onto an Lcd. I used a i²c lcd for this project.

• Sensor:

pin 1 - 5
pin2 - 5v
pin3 - GND

• LCD:

SDA - A4
SCL - A5
GND - GND
VCC - 5V

Step 4: Third Sketch

The final sketch also displays a realtime clock to the lcd. It uses a DS1302 module. For more information about this clock you can check out the Arduino clock I made in a previous project.

• Sensor:

pin 1 - 5
pin2 - 5v
pin3 - GND

• DS1302

RST - 2
DATA - 3
CLK - 4

• LCD:

SDA - A4
SCL - A5
GND - GND
VCC - 5V
